Medical surgical scissors used in cardiovascular surgery

Abstract

The invention discloses a pair of medical surgical scissors used in the cardiovascular surgery. The pair of medical surgical scissors comprises fixed plates, an angle adjusting unit, a dismounting unit and a telescopic unit, wherein the number of the fixed plates is two, the middle parts of the two fixed plates are correspondingly provided with mounting holes, inside bearings of the two mounting holes are connected with pin shafts, the angle adjusting unit comprises rotating shafts, a rotating disc, clamping holes and fasteners, and the corresponding side surfaces of the two fixed plates are provided with mounting grooves. The mounting grooves are located above the mounting holes, the side edge portions of the fixed plates are provided with connecting holes, the connecting holes are communicated with the mounting grooves, inside bearings of the connecting holes are connected with the rotating shafts, the end faces of the rotating shafts are fixed to the side face of the rotating disc,the end edge portion of the end face of the rotating disc is provided with six clamping holes, the bending angle of the blood vessel scissors can be adjusted, and the blood vessel scissors can be disassembled; and the length of the blood vessel scissors can be adjusted.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a medical cardiovascular surgical scissors. Background technique [0002] Surgical scissors are one of the indispensable and important instruments in doctors' surgical work. Common surgical scissors include tissue scissors, comprehensive scissors, fine scissors, vascular scissors and anatomical scissors. In the process of treating cardiovascular diseases, vascular scissors are often used for scissors. Cutting, the cutting head of the existing vascular scissors mostly presents a bending angle, and the bending angle cannot be adjusted. In order to meet the needs of different scenarios, when using it, it is necessary to bring a variety of bending angles according to the needs of different scenarios. The vascular scissors are very inconvenient, and the existing vascular scissors are not detachable. When a part of the vascular scissors is broken, the entire vascular scissors ...

[0002] Surgical scissors are one of the indispensable and important instruments in doctors' surgical work. Common surgical scissors include tissue scissors, comprehensive scissors, fine scissors, vascular scissors and anatomical scissors. In the process of treating cardiovascular diseases, vascular scissors are often used for scissors. Cutting, the cutting head of the existing vascular scissors mostly presents a bending angle, and the bending angle cannot be adjusted. In order to meet the needs of different scenarios, when using it, it is necessary to bring a variety of bending angles according to the needs of different scenarios. The vascular scissors are very inconvenient, and the existing vascular scissors are not detachable. When a part of the vascular scissors is broken, the entire vascular scissors need to be replaced, which greatly wastes materials, and sometimes the vascular scissors are damaged during the operation. The length also has certain requirements. The length of the existing vascular scissors cannot be adjusted. If the length is not enough, it can only be replaced with a new vascular scissors, which greatly affects the efficiency of the operation.
